Well, slightly off-topic, but European Defys seem to have other RF parts for 3G, but it's not impossible to get 3G working with AT&T in the States...

I had during my trip to the East Coast quite often 3G, but never full signal (max 4 out of 5 bars) with the T-Mobile 3.4.2 baseband on my German Retail Defy+. Screenshot was made in a motel in Montauk, the signal was very weak at all (even with EDGE) over there.

But I always just assumed that all handsets of Defy, regardless of where they are sold, have the ability to use any of the types of networks ("Quad band" right?). Anyway this is all just speculation...as long as my defy works on my network, I'm happy

EDIT: Even within just Defy or just Defy+, if radios were incapable of tuning into the HSDPA frequencies other than of that region, then there would have been many complaints from people who have flashed different region's SBF's..so my (inexperienced) guess is that Defy can connect to all HSDPA bands. Just this afternoon I read an article somewhere about some US carrier releasing an update to a couple of their android handsets to make them quadband...until now they were marketed as dual band and non global. Maybe same for Defy?

If I read the specs of the Defy, right from Motorola's site, I understand:

NETWORKS:
WCDMA 900/2100 <--> At least dualband for WCDMA
GSM 850/900/1800/1900 <--> Quadband for GSM
HSDPA 7.2 Mbps (Category 7/8), EDGE Class 12, GPRS Class 12, HSUPA 2.0 Mbps

So, I understand that this particular Defy model is only Quadband for GSM, while it is only Dualband for WCDMA. Although I remember there is a Defy in some country with 3 bands for WCDMA. I can't remember which one though.

Just found that in Spain it is stated as triband for WCDMA:

WCDMA 850/1700/2100
GSM 850/900/1800/1900

Hmm... Well any specs from moto, I'd take with a grain if salt
Anyway guess we'll know for sure if someone actually travels somewhere else and tries it out...

Question Are these fixes different from the baseband switcher?
hi...i would like to know if these fixes are any different from the baseband changer app that is being used in the CM9 nightlies...if yes then would these be able to give better connectivity in India for 2G/3G?

I guess those I posted here should be included in the app. Thus thread was previous to the app, now it's probably easier to use the app.

HSDPA is one type of HSPA networks.
If you're getting HSPA:11 then all well.

All I can see is "HSPA" not "HSPA :11"

thanks

The colon and number after HSPA is new as of ICS. I wouldn't expect to see that on a Defy.
